About 12 meters long, four meters high at the hip and weighing between six and nine tons, he Tyrannosaurus rex It is the best-known prehistoric predator on Earth. A fearsome and magnificent carnivore, it nevertheless walked at a speed of about 4.6 kilometers per hour: similar to that of humans. This is the conclusion reached by a scientific team from the Netherlands. They did not focus on the legs or hips of this tyrannosaurid theropod dinosaur from the late Cretaceous period, but rather on the swinging of its tail. Although other studies had already analyzed the locomotion of the Tyrannosaurus rex When not hunting or running, the tail's role didn't stand out in the final calculations. Despite the fact that it accounted for more than half of its length and could weigh 1,000 kilos, the new study has been published in the journal Royal Society Open Science.
